WHEAT STEAMER, HEATER, AND DRIER.

SPECIFICATION forming part of Letters Patent No. 245,602, dated August16, 1881.

Application filed June 3, 1881.

To all whom it may concern:

Be it known that I, RENSSELAER W. BAR- TON, a citizen of the UnitedStates, residing at Appleton, in the county of Swift and State ofMinnesota, have invented certain new and useful Improvements inSteaming, Heating, and Drying Wheat for Grinding 5 and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being bad to theaccompanying drawings,and to the letters or figures of reference markedthereon, which form a part of this specification.

My invention relates to wheat or grain heaters, steamers, and driers;and it consists of the following-described devices:

The object of my invention is to enable the operator to heat, steam,anddry the grain preparatory to grinding the same, or to heat and dry itwithout steaming it, at the will of the operator.

I attain the objects of myinvention by means of the devices illustratedin the accompanying drawings, making part of this specification.

Figure I is a side elevation of the case containing the heating andsteaming chambers, partly in section, and showing the inductionpipes forheated air or steam. Fig. 2 is a vertical section on the line a; ofFig. 1. Fig. 3 is a perspective of the heating, steaming, and dryingchambers, with the external case removed and a portion of the end of theheating and steaming chamber broken away to show interior structure.

The same letters and numerals are employed in all the figures inindication of identical parts.

A is a suitable case, preferably made of metallic plates, which incasesthe cham bersG and D, and is provided with the grain-hopper B and thesliding exhaust-valves E E.

D is the pipe conductin g a blast of hot air. This pipe is connectedwith the perforated pipe D which is located centrally and longidinallyin the hot-air space D of the chamber D. This pipe is provided with avalve, d, by which to regulate the passage of hot air into this chamber.V

A branch pipe, 0, is connected with the pipe D outside of the valve 01,and it is pro- (No model.)

To provide steam for the chamber O, I force a suitable supply of waterinto the heated air in pipe 0 at the water-pipe connection 0whiclii'sfconverted into steam and driven into chamber 0. These chambersare separate, elliptical in form, with their greater diameter vertical,and chamber 0 located above chamber D. The inner walls, 0 d, of eachchamber are perforated throughout, and the outer walls, 0 (1 areperforated upon their lower sides, 0 and (1 These walls are separated,formingagrain-spacc,B,between them, which is of uniform sizefrom thehopper B to the exitpipe 13 As the grain is passing through thegrain-spaces B the hot-air blasts may be applied to it in one or both ofthe chambers, or by admitting water into the induction-pipe G the heatedair therein would convert it into steam, and thus steam the grain in thepassages around the chamber C, while the heated air might or might notbe applied to the grain while passing chamber D, at the will of theoperator. I regulate the exhaust of the heated air or steam blast byadjusting the exhaustvalves E.

The perforated pipes O and D may be dispensed with, and the blast ofheated air or steam be delivered by the pipes D and 0 direct into theirrespective chambers.

' There are chutes c e, which engage the 10 wer portion of the outercase of chamber D, and extend outside of the caseAto deliver the dustand foreign substances separated from the grain by the steam and hot-airblasts, which, in practice, I find is an important feature of myinvention.

Having thus described my invention, what I claim as new in grainsteamers, heaters, and driers, and for which I desire to obtain LettersPatent, is-- 1. The separated chambers G and D, con structed with inner.perforated walls, 0 and d,

and the outer walls, 0 and d perforated at chambers O and D, havingperforated walls 0 In their lower sides, 0 and d, as and. for the purand(1 as and for the purposes substantially poses substantially as setforth. as set forth.

2. The steaming-chamber O, in combination In testimony whereof I affixmy signature in with the heating and drying chamber D, )ropresence oftwo witnesses.
